Crumbling Colours?

Plastics are produced from oil. Microplastics are tiny particles of these now ubiquitous materials. They are everywhere (in human bodies, all food chains and even rain drops) with probable negative effects on health. A 3-year Leicester University study, found that UV light (as in sunlight) causes brightly-coloured (red, green and blue) plastics to crumble much more quickly than black, white or silver alternatives. This, of course, means the brightly-coloured versions more speedily decompose into microplastics (https://www.theguardian.com/environment/article/2024/may/27/ditch-brightly-coloured-plastic-anti-waste-researchers-tell-firms). Waste researchers, not unreasonably, suggest that manufacturers should (where possible?) ditch brightly-coloured plastic items. Perhaps someone should tell Lego?
